In order to have your alerts play in Stream buddy you have to setup an overlay in StreamElements or any other service you use for alerts and add that overlay to Stream buddy as a Tab.
Using StreamElements
- Login to StreamElements and go to Streaming tools > Overlays.
- Choose an existing or create a new Overlay.
- In the Overlay editor, click Add widget > Alerts > AlertBox.
- In this widget you can setup Sounds/Alerts as you want.
- When you are done press Save.
- Finally right of the Preview button there is a Chain icon which you can click to copy the Overlay URL. This is the link you have to put in the Stream buddy Tab.
